What bass configurations does this pickup fit?

The LJAX measures 93.99mm in length and 18.54mm in width, fitting standard bridge positions on most basses. It supports four and five-string configurations with a maximum recommended string width of 69.2mm, and the radiused magnet structure ensures balanced output across all strings without dead spots.

What comes in the box and what do I need to install it?

The package includes the pickup, a prewired volume and active tone control set, Quik-Connect cable, battery clip set, output jack, and adjustment screws for magnetic field tuning. The solderless-compatible wiring system makes installation straightforward without requiring soldering.

How does the X-Series preamp differ from other active pickups?

The X-Series preamp operates on a single 9V battery and eliminates the soft limiter found in previous EMG designs, giving you full dynamic range and peak headroom. This means you capture more of your playing dynamics and transient detail without compression limiting your peaks.

Is this pickup good for jazz or vintage tones?

The LJAX is engineered for modern, articulate tones and works best in funk, modern rock, studio sessions, and live performance. It is not designed for traditional jazz or vintage tone purists looking for warmer, less aggressive characteristics.
